UNITED STATES PATENT Omron.

IMPRovl-:M ENT IN T oBACCo-SCREWS.

Speeication forming part of Letters Patent No. 27,631, dated March 2T,1860.

To all whom t may concern.-

Be it known that we, N. Holler and W. H. TAPPEY, of the city ofPetersburg, county of Dinwiddie, and State of Virginia, have invented anew and useful Improvement on 'a Tobacco-Screw; and we do hereby declarethat the following is a full, clear, and exact description of theconstruction and operation of the same, reference being had to theannexed drawings, making a part of this speeication,

Figure A is a horizontal section of the topplate. Fig. B is a horizontalsection of the under plate. Fig. C isa vertical section of A and Bconnected. l

Similar letters of reference indicate corresponding parts in the threefigures.

Our invention consists in the construction of two plates with slats andkey for the purpose of supporting a heavy lever in tobaccopress screws.

D represents the body of the screw, with the plates A tted loose and theplate B keyed tight thereon.

E represents six slots or openings, as shown in Fig. B, in which a key,F, rises and falls alternately as the lever G, with plate A, movesbackward and forward. By reversing the key F the motion of the screwwill likewise be changed, so as to move up or down.

H is a turned disk in Fig. B, raised for plate A to work thereon. Thebackward motion of plate A causes key F to rise by means of the bevelpoint I, and consequently drops into each succeeding slot or opening.

The operation will be readily understood. By turning plate A by means oflever Gthe key F will alternately move up and down, and cause plate B,with screw D, to be operated as desired.

The above implement is extremely cheap, simple, and works well.

Having thus described our invention, what we claim as new, and desire tosecure by Letters Patent, is

The arrangement of the several parts conibined as constituting thespecific machine, for the purpose shown and set forth.
